A few cheap tricks on the 5.0 are a cam, a high flow exhaust and a good ignition. The factory setup on all fords during the 80s was highly restrictive. Most of this can actually be found in the muffler itself. Pull that, bolt on a $30 turbo muffler, youll feel the difference. As for the cam, Crane has a few decent cams for that particular 5.0. With a 6500R redline(dont quote this) this is a heavy breathing engine. As such, a little lift goes a long way. As far as the cold-air intake, thesals hit it dead on. The factory box tends to collect heat directly under the filter. There are a few ways to cure this problem. Either run a direct out plumbing setup, but if you live in a dusty area this is a bad idea due to lack of filtration. My personal suggestion is this. Off the outside of the air intake, run a hose directly to your fender. Cut out a hole to match your hose, and you have an external air draw. Just be sure it doesnt point directly down. As for your ignition, a good high-voltage coil will do wonders. Just be sure to replace the cap/rotor/wires with a quality set and it should hold up nicely. Finally, replace every rubber vacum line on this motor as soon as possible. With nearly 20 years of use, the first thing to go on these motors is the vacum lines. Huge power loss. In the process, it may be wise to replace the PCV valve and EGR valve. The PCV is found on the back near the firewall. Chances are good that the seal is bad. Its a 1-2 inch rubber gromit, very easy to replace. As for the EGR, its on the side of your plenum near the throttle plates. You may want to replace it, you may want to dis-engage it, thats your choice. A effective move for the EGR is to clean it with a knife you dont care about. But when its $15 for the new one, its ultimatly your call. Hope this Helps.
Thanks a bunch drg84. I have not kept up with the hot Rod industry since the late 70's. Had kids to educate etc. You have been extremely helpful. I just can't drive a guzzler with no power.
